lttEMUVABLE VALVE SEAT FOR TA'UGET%.

Application filed March t, 19M. serial 1to. 450,520.

To all whom it may concern.-

Be it known that ll, FRANK J. SnnAsnA, a citizen of Poland, residing atWestfield, in the county of Hampden and State of Massachusetts, haveinvented a new and useful Removable Valve Seat for Faucets, of which thefollowing is a specification.

My invention relates to improvements in valve construction, and moreparticularly 'to the valve-seats for faucets and the like, and residesin an independent and separable or detachable valve-seat mounted on apackingring which in turn is mounted on an annular flange in the valvecasing, a hollow member inserted in said casing above said seat to retain the same in place, said member bein perforated for the passage ofwater through one side thereof, and. removable means to retain saidmember in position, together with a valve and valve-stem, the necessarypacking members, and such other parts and members as may be needed orrequired in order to render the device complete in every respect, all ashereinafter set forth.

The primary object of my invention is to produce a comparatively simpleand inexpensive, strong, and efficient, removable valve-seat andcorrelated and associated ltd "be lone.

--.This valve-seat and its correlated and associated parts and membersare compact, and when properly assembled are tight and capable of givingas good or better service than is obtainable when the valve-seat is anintegral part of the valve casing. Other objects and advantages willappear in the course of the following description.

I attain the objects and secure the advantages of my invention by themeans illustrated in the accompanying drawings, in

; which- Figure 1 is a central, longitudinal, vertical section through afaucet in or with which is incorporated a removable valve-seat thatembodies a practical form of my invention; Fig. 2, a transverse,vertical section through sald faucet at right-angles to that whichappears 1n the preceding view, and taken on the aXIS Of the valve-stem;Fig. 3, a plan of the vertical chamber and contents thereof of saidcaslng, looking down into said chamber, and Flg. 4, a cross sectionthrough the top port on of the valve.

Snnilar reference characters designate similar parts throughout theseveral views.

The casing, valve and valve-stem, and connections between said stem andsaid casing, of the faucet herein shown and do scribed, are of old andwell-known construct on, and only said casing and the cap-nut are shownin section in the drawings.

A valve or faucet casin is represented at 1, the inlet to suchcasingieingat 2 and the outlet thereof being at 3, and said casinghaving a vertical chamber 4. The inlet chamber 1s separated from theoutlet chamber in the casmg 1 by interior vertical walls 5 and 6 and aperforated horizontal member between and connecting said walls, whichmember forms an annular flange 7. Water entering the casing 1 and 2,passes under the wall 5, upward through the opening formed by the flange7, and over the top of the partition 6, to escape at the outlet 3. a

The faucet is provided or equipped with a valve-stem 8 and a valve 9 ofthe type where in the valve-stem rotates without reciprocation and thevalve reciprocates without rotation. The valve-stem 8 is provided withan integral or fixed collar 10, and there are packing-rings 11 and 12respectively above and below said flange, on said valve-stem. Acompression spring 13 encircles the valvestem 8 below the packing-ring12. On the bottom of the valve 9 is a disc or packing 14 of fiber,rubber, or other suitable material.

The packin 14 is held in place against the bottom of the valve 9 bymeans of a nut 15. A 'cap-nut 16 fits on to the valve-stem 8 above thepacking-ring 11, and has an interiorly Screw-threaded part 17 to engagethe upper terminal of the wall of the chamber 14, which latter isexteriorly screw-threaded for that purpose. The cap-nut 16 is suitablyshouldered to engage the packing-ring 11, the flange 10, and thepacking-ring 12. The packing-ring 12 is of suflicient size to fit overthe upper edge of'the wall of the chamber 4,

so that, when the cap-screw 16 is screwed tightly into place, thepacking-ring 12 is compressed between said nut and wall and seals thejoint between these two members. Likewise the packing-ring 11 iscompressed between the engaging parts therefor of the cap-nut 16 and theflange l0 and seals the joint between the valve-stem 8 and said nut. Asalready observed or will be understood, the parts and members thus fardescribed in detail are generally old and well known.

The new elements of thedevice comprise a perforated cushion orpacking-ring 18 of suitable material, a disc having a central openingtherethrough which constitutes a valve-seat 19, and a cylinder 20. Thepacking-ring 18 is seated on the flange 7 and held in place bysurrounding portions of the partition members in the casing 1, includingthe wall 5 and a portion of the wall 6 which extends above the flange 7The valve-seat 19 is mounted on the packing-ring 18; and said seatpreferably has on top thereof surrounding the opening therein a flange21, as is customary with valve-seats in connection with which packingprovided valves are used.

The cylinder 20 is a retaining member for the valve-seat 19 and when theparts are assembled rests on top of said seat adjacent to the peripherythereof. Said cyllnder has a sliding fit in the chamber 4. There is anopening 22 in the side of the cylinder 20 at the base to establishcommunication between the chamber 4, or rather between the cylinder andthe outlet chamber in the casing 1. The cylinder 20 is held in place bythe spring 13 which is of a size to permit the same to rest on the upperedge of said cylinder. The spring 13 is forced into contact with thecylinder 20 by the packing-ring 12, when the cap-nut 16 is screwed ontothe wall of the chamber 4 and tightened.

It is necessary to lock the cylinder 20 against rotation, otherwise thecylinder would be liable to have its position changed so as to locatethe opening 22 in such a. manner that communication from the chamber 4or the interior of said cylinder, through such opening, into the outletchamber in the casing 1, would be wholly or partially cut off by thecylinder. To this end there are oppositely-disposed, longitudinal slots23 in the cylinder 20 and oppositely-disposed, vertical slots orrecesses 24 in the wall of the -chamber 4 to receive oppositely-disposedlugs 25 on the valve 9, which lugs are common to Valves of thischaracter. The lugs 25 extend through the slots 23 into the recesses 24,thus locking the cylinder 20 to the wall of the chamber 4, and at thesame time holding the valve 9 against rotation. The lugs 25 are, ofcourse, free to move up and down in the slots 23 and recesses 24 whenthe valve 9 is opened and closed, by means of the valve-stem 8, in theusual manner.

The flange 10, located as it is between the packing-ring 11 which isconfined by the cap-nut 16, and the parts and members low said flange,is prevented from moving longitudinally, and in turn prevents thevalve-stem 8 from so moving.

In assembling the parts, the packing-ring 18 is first placed in positionon the flange 7, next the valve-seat 19 is placed on said packing-ring,with the flange 21 directed upwardly, then the cylinder 20 is introducedinto the chamber 4 on top of said valve-seat, care being taken to havethe slots 23 in alignment with the recesses 24 and the opening 22directed toward the outlet end of the casing 1. After the introductionof said cylinder the valve 9 is inserted in the casing in said cylinderand the cap-nut 1(5 placed over the top of the wall of said chamber, andfinally said nut is screwed down tightly on said wall to force thespring 13 down on top of said cylinder and compress the packing-ring 12between the flange 10 and the top of said wall. When introducing thevalve 9 with the lower terminal portion of its stem 8 into the cylinder20, it is necessary to insert the lugs 25 in the slots 23 and recesses24. The faucet is now ready for use like any other faucet.

Vhile the valve 9 is open, as shown in Figs. 1 and 2, the water flowsfrom the inlet chamber in the casing 1, through the openings in theflange 7 the packing-ring 18, and the valve-seat 19, into the cylinder20, and through the opening 22 in said cylinder, into the outlet chamberin said casing. When the valve 9 is closed, by turning the valve-stem 8in the direction to force said valve downwardly into close contact withthe seat 19, or with the seat flange 21, the water is held back in theinlet chamber of the casing 1 and the flow thereof entirely out off fromthe outlet chamber in said casing, since the opening through saidvalve-seat is now ti htly and securely closed by the packing 14. Thevalve is raised from the seat to open the same by turning the valve-stemin the opposite direction.

When the valve-seat 19 becomes worn so that leakage occurs, or when forany other reason it be necessary or desirable to remove said seat, thecap-nut 16 is unscrewed from the wall of the chamber 4 to release theparts confined thereby, and web parts, including the valve-stem 8, valve9, spring 13, and packing-rings 11 and 12, are removed with said nutfrom the casing. The cylinder 20 now being exposed as well as releasedcan be drawn upwardly out of the chamber 4, and the valve-seat 19 takenout throu 11 said chamber. After removing the cylin er 20 and valve-seat19, the same or another, valve-seat, as occasion demands, is replaced orplaced on the packing-ring 18, the cylinder 20 is returned to position,and the other parts of the faucet are reassembled, so that said faucetis once more ready for operation in the usual manner.

if necessary. i

The opening 22 and slots 23 must be in such relationship that, when theformer is in position to open a way into the outlet chamber in thecasing 1, the latter are in position to receive the lugs 25 and at thesame time permit said lugs to enter the recesses 24:.

The threaded terminal of the valve-stem 8, with which the valve 9 isengaged, appears at 26 in Fig. 2.

Although more or less change in the shape, size, and other features ofthe removable valve-seat and correlated and associated parts andmembers, as here presented, may be made without departing from thenature of my invention or exceedlng the scope of what is claimed, ll amaware that faucets have been provided with removable valve-seats, and donot,therefore, seek to claim broadly such a construction.
